Dissemination and Transmission of the E1-226V Variant of Chikungunya Virus in Aedes albopictus Are Controlled at the Midgut Barrier Level
Figure 5
Unbalanced proportions of E1-226V and E1-226A provided in blood-meals to Ae. aegypti (AAPT) and Ae. albopictus (ALPROV). Ae. aegypti and Ae. albopictus were given an infectious blood-meal containing unbalanced proportions of two clones E1-A and E1-V isolated from the strains E1-226A and E1-226V, respectively.
Two mixes were tested: one containing 1∶9 (E1-A:E1-V) and one containing a mix of 9∶1 (E1-A:E1-V). At day 7 post-infection, dissemination (A) and transmission (B) were examined by estimating the proportion of E1-V in wings and saliva, respectively, of five individual females. Error bars show the confidence intervals (95%).
